The B-PROACT1V project is a British Heart Foundation (BHF) funded longitudinal study concerning physical activity and screen-viewing patterns of children and their parents. The first phase of this project took place between January 2012 and May 2013 where data were collected from 1456 Year 1 children (5-6 years) and their parents from across 57 schools in the Bristol, Bath (BaNES) and North Somerset area. Analyses of these data showed that parents play an important role in influencing their children’s physical activity and screen-viewing behaviours.

The research team returned to the same schools in March 2015 to July 2016 to measure the changes in physical activity and screen-viewing behaviours of the children now they are in Year 4 (8-9 years old). 47 schools were recruited during this phase, with 1224 children and their parents consenting to participate.

When the same group of children are in Year 6 (10-11 years) the team will begin the third phase of the project (March 2017 to July 2018) and once again measure physical activity levels and screen-viewing patterns of the children and their parents. The project continues to focus on identifying the key behaviours that parents use to help their children to be more physically active. This information will then be used to develop strategies that enable parents to encourage their children to be as active as possible. 


The participants for the next phase of study are Year 6 children and their parents from 57 schools within the Bristol, BaNES and North Somerset area (visited in Phase 1 & 2), many of whom took part in the original study in 2012/2013 and/or the second phase in 2015/2016. In addition, we are also recruiting other Year 6 children within these schools, who did not take part in the first phase of the project, to join the study.  


In the next phase of the project, we ask all the participating Year 6 children and their parents to wear an activity monitor (accelerometer) for 5 consecutive days (3 weekdays and both weekend days). The data from these monitors will be processed to provide information about overall levels of physical activity as well as when that activity takes place. We also assess the children’s height, weight and blood pressure, and ask both the children and their parents to complete a survey. The parental survey looks at what parents do to help their children to be active, and the child survey looks at how their social networks influence their decisions around physical activity.

The data from the project will be used to identify how patterns of physical activity and screen-viewing change as the children get older and what parents can do to help their children to be physically active.
